There are definitely plenty of Mexican restaurants around if you drive a couple of miles on Pearl (Cozumel, Los 4 Amigos, Gran Fiesta) and we've eaten a whole lot at each of them! But we only go back to one now and that is Los 4 Amigos.
The chips and salsa here are the best; it's more tomato and less onion, always a plus for me. On top of that they also bring an additional dipping sauce that is like a spicy ranch which is delicious also.
The quality of their meat cuts I think is also superior; my wife always gets the carne asada and they give huge portions. The rice and beans are top notch to, so they really nail down the essentials. I like their macho burrito which tops a burrito with queso and pineapple (this makes it healthy to me).....they do a lot of pineapple dishes and I was weary of it at first (cheese covered pineapple?) but this whole sweet and salty combination was amazing!
We almost always get a free dessert to, so who can be upset with free sopapillas?! Really nice and genuine staff; it's the only place that can be busy but not be insanely loud that you can't hold a conversation with someone near you. All 3 are good restaurants but this one has definitely separated itself from the pack for us.
